1.Diagnostic Accuracy of Machine Learning Algorithms for Hepatitis A Antibody
Korean Journal of Aerospace and Environmental Medicine 2022;32(1):16-21
Purpose:
The objective of this study was to develop a model for predicting the positivity of hepatitis A antibody based on nationwide health information using a machine learning technique.
Methods:
We used a data set that included the records of 4,626 samples. the data was randomly divided into a training set 80% (3,701) and validation set 20% (925).Customized sequential convolutional neural network (CNN) model was used to predict the positivity of hepatitis A antibody. The loss and accuracy of this model was calculated.
Results:
This model has 12-input and 2-concatenate and 3-dense layers. The total parameters of this model were 1,779. The accuracy quickly reached to over 85% validation accuracy in 50 epochs. The train loss, train accuracy, validation loss and validation accuracy of this model were 25.4%, 89.5%, 29.0%, and 87.2%, respectively.
Conclusion
The model derived from the sequential CNN model exhibited a high level of accuracy. This model is a useful tool for predicting the positivity of hepatitis A antibody.
2.Outcome of Delayed Decompression Surgery for Cauda Equina Syndrome secondary to Lumbar Disc Herniation: A Case Report
The International Medical Journal Malaysia 2019;18(2):113-116
Cauda equina syndrome (CES) is a constellation of symptoms which consist of low back pain, sciatica, saddlearea paraesthesia, urinary or faecal incontinence, with or without motor weakness, and sensory deficit.
Surgical decompression is indicated as soon as possible, as decompression within 48 hours from onset allows
maximum improvement of symptoms. Recovery usually occurs months or years postoperatively. We report
a case of a patient with cauda equina syndrome secondary to massive lumbar disc herniation who had
undergone urgent decompression one week after onset of urinary and bowel dysfunction. The clinical
outcome post surgery was also discussed.

4.Postmenopausal Osteoporosis: Screening & Diagnosis based on FRAX® and BMD
The Singapore Family Physician 2021;47(3):5-7
Osteoporosis is a common ailment, especially in older women, yet it is one of the most under-diagnosed and undertreated diseases. Screening of patients, therefore, is invaluable to identify those who require further evaluation. We shall discuss who requires screening and further evaluation of osteoporosis and discuss the diagnosis of osteoporosis.
5.Moving it for Weight Loss
The Singapore Family Physician 2021;47(5):30-35
The rate of overweight and obesity is increasing worldwide, with significant health impact. Obesity is a risk factor for morbidity and mortality and weight loss should take a multi-pronged approach, including dietary control and physical activity. The lack of physical activity, sedentary behaviour, as well as poor cardiorespiratory fitness are all independent risk factors for morbidity and mortality as well, thus it is important to advise lifestyle changes to address these issues. Most individuals who have no contraindications can embark on light- to moderate-intensity physical activity without the need for medical clearance. Specific advice on physical activity should be given, targeting the individual, and this can be done using the FITT (frequency, intensity, time, type) principle. Physical activity should also be reviewed regularly and progressed gradually to target physical activity guidelines. Individuals should also be encouraged to replace sedentary behaviour with at least light-intensity physical activity whenever possible.
6.Antibiotic Stewardship
International e-Journal of Science, Medicine and Education 2012;6(supp1):S75-S79
The discovery of antibiotics had been one of
the most significant events in the history of medicine.
Antibiotics had saved countless number of lives and
had contributed significantly to the health of mankind.
The emergence of resistance is however a major threat
to the continued usefulness of antibiotics. There are
now strains of bacteria which are resistant to virtually all available antibiotics and these strains are increasingly
being encountered in clinical practice. The development
of new agents had not kept pace with resistance and
it is unlikely that there will be major breakthroughs
in the near future. The world needs to conserve and
prolong the useful lives of the existing agents. This can
only be achieved through good antibiotic stewardship
programmes. As antibiotic resistance is a global threat
all major stakeholders have to work together to meet
this challenge.
7.Changing trends in informed consent
International e-Journal of Science, Medicine and Education 2014;8(1):3-7
Consent is defined as the “voluntary
agreement to or acquiescence in what another person
proposes or desires”. In the context of medical practice
it is now universally accepted that every human being of
adult years and of sound mind has the right to determine
what shall be done with his or her own body. Informed
consent is now a central part of medical ethics and
medical law. There has been a change in the public’s
expectations of their role in medical decision making.
The paternalistic approach by doctors is no longer
acceptable. Today the patient has the right to receive
and the doctor the obligation to give sufficient and
appropriate information so that the patient can make an
informed decision to accept or refuse a treatment option.
This has led to higher standards of practice in the process
of informed consent taking. Consent taking is both a
legal and moral requirement. Failure to comply with
standards of practice can result in criminal prosecution,
civil litigation or disciplinary action by the relevant
professional authority. Consent taking is a process and
not merely a one-off affixation of the patient’s signature
on a consent form. It involves a continuous discussion
to reflect the evolving nature of treatment from before
the treatment is given to the post-operative or discharge
period. The regulatory authorities in many countries
have established standards for consent taking which
would include the capacity of the patient, the person
who should seek consent, the information to be provided
and the necessary documentation.

10.Leptospirosis: a re-emerging infection
The Malaysian Journal of Pathology 2011;33(1):1-5
Leptospirosis is a re-emerging zoonotic infection. In developing countries large outbreaks have
occurred in urban slums and following fl oods. Individuals from developed nations are also now
more frequently exposed to the infection as a result of international travel and greater participation
in certain outdoor recreational activities. Leptospirosis remains a diagnostic challenge since it often
presents as a non-specifi c febrile event and laboratory diagnosis is still currently inadequate. Rapid
tests may not be suffi ciently sensitive in early disease and culture facilities are not widely available.
A severe pulmonary haemorrhagic form of the infection is increasingly being encountered in many
countries including Malaysia. The control of leptospirosis is largely dependent on general hygienic
measures and rodent control. An effective human vaccine is still not available. There remains much
that is unknown about this disease and there is scope and opportunity for good quality research.
